Have you tried going through xorg.conf and just changing all of the relevant
0s to 1s and vice versa?

Actually, the first thing i would try would be to change these lines in the
Server Layout section:

    Screen      0  "Screen0" 0 0
>     Screen      1  "Screen1" RightOf "Screen0"


    Screen      1  "Screen0" 0 0
    Screen      0  "Screen1" LeftOf "Screen0"
